Fused Quartz Glass Double Sphere Flask with Grounded Milliliter Scale

Fused Quartz Glass Double Sphere Flask with Grounded Milliliter Scale

The production method of Fused Quartz Glass Double Sphere Flask is more complicated than that of ordinary quartz flask. In order to meet the purpose of the experiment. First of all, we have to accurately calculate the volume of each sphere and the middle dredge pipe, and make accurate calibration. Generally, for the sake of the durability of Quartz Glass Double Sphere Flask, we will choose a thicker quartz tube for the middle connecting tube. In the welding process, it must be a one-time success. The two spheres are blown by a mold, so they will have a more accurate volume. We can produce quartz flasks of different sizes and shapes according to customers’ requirements. Welcom to inquiry.

Fused Quartz Glass Features:

Fused quartz glass is a special industrial glass made of silicon dioxide. It is a very good basic material. Quartz glass has a series of excellent physical and chemical properties.

1. High temperature resistance. The softening point of fused quartz glass is about 1730℃ and can be used for long time working under 1100℃~1250℃.  And working at 1450℃ in a short time.

2. Corrosion resistance. In addition to hydrofluoric acid, fused quartz glass is inert to other acids. Its acid resistance is 30 times as ceramic, 150 times as stainless steel. Especially, any other material cannot make a comparison with chemical stability of fused quartz at high temperature

3. The thermal stability is good. Thermal expansion coefficient is extremely small. And it can withstand severe temperature changes such that heating up to 1100℃ and putting it in normal temperature water will not crack.

4. The light transmittance is good. Quartz glass has good transmittance in the whole spectral band from ultraviolet to infrared. The transmittance of the visible light is above 95%. Especially in the ultraviolet spectrum band and the maximum transmittance is over 85%.

5. The electrical insulation performance is good. Resistance value of quartz glass equaling to 10000 times of ordinary glass. It is an excellent electrical insulating material and has good electrical properties even under high temperature.

As a leading China fused quartz glass supplier and manufacturer, we are providing best price as well as quality for all kinds of customized fused quartz products. We are also willing to look for long term partners who are a distributor or wholesaler specialized in fused quartz glass in local.
